PWM DACs
(continued)
DAC0 & DAC1 are shared with ADC2 & ADC3 input pins respectively. If ENADC2/
3
bit in the ENADC control register is
cleared to LOW, A/D converters will activate simultaneously. After the chip is reset, ENADC2/
3
bits will be in HIGH state
and DAC0 & DAC1 will act as PWM output pins.
DAC4 & DAC5 are shared with SCL1 & SDA1 I/O pins respectively. If users clear the
ENDDC
bit in the CH1CON control
register to LOW, channel 1 of DDC will be activated. When used as DDC channel, the I/O port will be an open drain structure
and include a Schmitt Trigger buffer for noise immunity. After the chip is reset,
ENDDC
bits will be in HIGH state and DAC4
- DAC5 will act as PWM output pins.
